Answer:

2x^2+2x+2 or 2(x^2+x+1)

Step-by-step explanation:

C = 2x^2+5x-1

D = x-1

C-3D = (2x^2+5x-1) - 3 * (x-1) =2x^2+5x-1-3x+3 =2x^2+2x+2 = 2(x^2+x+1)

The value of the equation C - 3D = 2 ( x²  + x + 1 )

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the value of the expression be A

Now , the value of equation C is

C = 2x² + 5x - 1

And , the value of equation D is

D = x - 1

So , the value of the equation C - 3D is given by

3D = 3 ( x - 1 )

3D = 3x - 3

So , the equation is

The value of C - 3D = 2x² + 5x - 1 - ( 3x - 3 )

On simplifying the equation , we get

The value of C - 3D = 2x² + 5x - 1 - 3x + 3

On adding the similar terms in the equation , we get

The value of C - 3D = 2x² + 2x + 2

Taking 2 as the common factor of the equation , we get

The value of C - 3D = 2 ( x² + x + 1 )

Therefore , the value of the expression A is 2 ( x² + x + 1 )

Hence , The value of the equation C - 3D = 2 ( x²  + x + 1 )

Answer:

Positive association

Step-by-step explanation:

You can see the weight go up by the model number going up, if you put it on a graph it will show the trend line going up.

So say

"This has a positive association because the weight is going up while the model # is going up. thus gives a positive association when graphed"

Answer:

Option D

Step-by-step explanation:

For addition we move right on the number line and for subtraction we move left.

So, (-7) represents a 7 units to the left from the zero.

Then move 10 units right from (-7),

Therefore, (-7) + 10 = 3

Or (-7) - (-10) = 3

Option D is the correct option.

Answer:

x=13 and y=15

Step-by-step explanation:

Let the 2 numbers be x and y

ATQ,

x+y = 28 ------ eqn.1

x-y=-2 -------- eqn.2

Adding both the equations:

x+y=28

+x-y=-2

_______

2x = 26

Therefore x=13

Now substituting the value of x in eqn. 1

x+y=28

13+y=28

Therefore y=28-13

=15

Step-by-step explanation:

The amount is 2.4, the base is unknown and the percent is 60%.

The base is the part of the problem that represents the "whole".

The given number 2.4 is 60% of another number which is unknown. Therefore, this unknown number is the base since it represents the whole.

Thus, we have found that the amount is 2.4, the base is unknown and the percent is 60%. The correct answer is option D.

Step-by-step explanation:

Answer:

[tex]the \: area \: of \: the \: logo \: is \: {91cm}^{2} [/tex]

Step-by-step explanation:

To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.

Area of the square.

To calculate the area of the square you have to calculate the square of one of its sides, following the formula:

[tex]a = {a}^{2} [/tex]

Where "a" is the length of one of its side.

The side length of the square is a=7cm, so its area will be:

[tex]asquare = {7}^{2} \\ asquare = {49cm}^{2} [/tex]

Area of the triangles.

The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.

To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:

[tex]a = \frac{b.h}{2} \\ a = \frac{7.4}{2} \\ a = \frac{28}{2} \\ a = {14cm}^{2} [/tex]

The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:

[tex]atriangles = 3a \\ atriangles = {42cm}^{2} [/tex]

Now that the area of all shape are calculated, you have to add them to determine the area of the logo:

[tex]alogo = asquare + atriangle \\ alogo = 49 + 42 \\ alogo = {91cm}^{2} [/tex]
